Bioaccumulation of lead in Volema (Pugilina) cochlidium from Bacoor Bay, Cavite

Abstract

This study focused on determining the lead concentration of the water and sediment obtained from the coastline of Sangley Point, Bacoor Bay, Cavite, and in the shells and hepatopancreas of the gastropod, Volema (Pugilina) cochlidium collected from the site. All samples were acid digested and underwent atomic absorption spectroscopic analysis to determine the lead concentration. Results of the ANOVA performed showed no significant difference between the lead concentration present in the snail shells and hepatopancreas and that present in the water and sediment samples, suggesting that the snail species is an efficient biological indicator.
